Gu1ll4um3r0m41n has discovered a vulnerability in BTI-Tracker, which can be exploited by malicious people to delete arbitrary files.

The include/prune_torrents.php script allows to perform certain actions via HTTP requests without checking for valid permissions. Additionally, input passed to the "TORRENTDIR" and "hash" parameter is not properly verified before being used to delete files. This can be exploited to delete arbitrary files.

The vulnerability has been confirmed in version 1.3.2. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly verified and permissions are correctly checked.
